Hyperoside is a chemical compound. It is the 3-O-galactoside of quercetin. Hyperoside has been isolated from Drosera rotundifolia, from the Lamiaceae Stachys sp. and Prunella vulgaris, from Rumex acetosella, Cuscuta chinensis seeds, from St John’s wort and from Camptotheca acuminata. Hyperoside (quercetin-3-O-galactoside) is a flavonoid compound mainly found in the herb plants Hypericum perforatum L and Crataegus pinnatifida. Although hyperoside has a variety of pharmacological effects including anti-viral, anti-oxidative, and anti-apoptotic activities, the anti-inflammatory mechanism of hyperoside in mouse peritoneal macrophages remains unclear. In this study, hyperoside was shown to exert an anti-inflammatory action through suppressed production of tumor necrosis factor, interleukin-6, and nitric oxide in lipopolysaccharide-stimulated mouse peritoneal macrophages.
